Freelance assassin John Rain (Shiina) is being hunted by the yakuza and by Holtzer (Oldman), the head of the CIA's Tokyo office, since both believe that Rain has a flash drive containing information on corrupt bureaucrats. Rain is a subdued guy for being so lethal and feared while Holtzer makes up for it by yelling all the time. There are some subplots that don't really go anywhere and the flick doesn't have as much action or thrills as an action-thriller should. Based on the first of Barry Eisler's 'John Rain' novels.
